Non-skid scaffold board pad

ABSTRACT

A scaffold board construction including pads for attachment to the underside of a scaffold plank to restrain the plank from slipping longitudinally or transversely on the plank-supporting bars of the scaffold, which bars are ordinarily tubular metal, and the pads are constructed of rubbery, non-skid material the pads being of two configurations, one thicker and channelled and the other thin and planar, the thicker pads having channels to accept and grip the bars, and the thin pads engaging other planks. For convenience in attaching the thicker pads they are formed with integral nailing strips permitting the pads to be quickly and semi-permanently secured to the planks, but both pads may be secured adhesively if desired. The preferred form of plank has the thicker channelled pad at one end and the planar pad at the other end for use in overlapping series.

Knox[5 7] ABSTRACT A scaffold board construction including pads forattachment to the underside of a scaffold plank to restrain the plankfrom slipping longitudinally or transversely on the plank-supportingbars of the scaffold,

which bars are ordinarily tubular metal, and the pads are constructed ofrubbery, non-skid material the pads being of two configurations, onethicker and channelled and the other thin and planar, the thicker padshaving channels to accept and grip the bars, and the thin pads engagingother planks. For convenience in attaching the thicker pads they areformed with integral nailing strips permitting the pads to be quicklyand semi-permanently secured to the planks, but both pads may be securedadhesively if desired. The preferred form of plank has the thickerchannelled pad at one end and the planar pad at the other end for use ioverlapping series.

2 Claims, 4 Drawing Figures NON-SKID SCAFFOLD BOARD PAD BACKGROUND OFTHE INVENTION Scaffold planks usually have flat or gently taperedundersurfaces and are often either laid loosely on the scaffold bars orties in place with rope. One or more planks laid side by side comprise aworking platform for workmen and material and the platform often has atransverse horizontal width less than the length of the correspondingscaffold bars so that the planks sometimes slip sidewise as well asencountering the move obvious hazard of longitudinal slippage. Metalcleats do not prevent sidewise slippage and require rather exactplacement of the scaffold bars to prevent rocking of the planks with theresult that such cleats are simply not used regularly. There exists aneed, therefore, for a non-slip plank or plank pad construction which isvery safe to use, convenient to adapt to existent equipment as well aseconomical to manufacture.

SUMMARY OF THE INVENTION As claimed, the herein disclosed item satisfiesthe abovementioned need inasmuch as scaffold planks are provided withpads on the underside surface, these pads being of resilient andnon-skid material with some of the pads having open channel portions atthe end of each plank to accept the scaffold plank-supporting bars andplanar pads at the other end of each plank. The pads have lateralnailing strips which are nailed onto the planks for substantiallypermanent securement of the pads or the pads maybe adhesively secured.

BRIEF DESCRIPTION OF THE DRAWING DETAILED DESCRIPTION OF A PREFERREDEMBODIMENT Referring now to the drawing and particularly to FIG.

2 and 3, the scaffolding is fragmentarily illustrated as 5 comprisingupright 10 and scaffold plank-supporting horizontal bars 12 secured tothe uprights as indicated at 14, the particular mode of securement ofthe bars 12 being somewhat immaterial to the structure and functioningof the invention claimed herein.

The planks 16 are of a lengthto span the space between pairs of bars 12and of course these planks may be of constant cross-section or taperedtoward the ends. As illustrated in FIG. 3 these planks will frequentlynot occupy the full inter-upright space on the bars 12 so that one ormore spaces 18 between the planks 16 or between the planks and theuprights will occur, this introducing the hazard of sidewise slippage inaddition to the hazard of endwise slippage of the planks 16.

According to my invention each plank will have secured to one side, theunderside in use, at least one pad generally indicated by the numeral20, these pads being of a length corresponding substantially to thewidth of the planks 16. The pads 20 are secured near the ends of theplanks and are constructed of slightly resilient, non-slip material suchas synthetic rubber. Each pad 20 has two lateral nailing strips 22 and athickened central portion 24 with an open channel 26 running the entirelength of the pad centrally of the thickened portion 24, and saidnailing strips 22 are similarly elongated in the same direction as saidchannel. The channels 26 are substantially semi-cylindrical to acceptand grip the bars 12, thus preventing the plank 16 from slippling eitherlongitudinally or transversely.

The nailing strips have spaced apertures 28 for nails or screwsindicated at 30 and the nailing strips are faired or radiused into thethickened portions as indicated at 32 to assure against rupture in use.The portions of the pads at the sides of the channel 26 have a veryconsiderable thickness for strength and durability and these portions atthe sides of the channel terminate in flat faces 34 of considerable areato withstand abrasion such as that encountered when the planks arestacked one on top of the other for storage and transportation.

The pads 20 are preferably secured to one end only of each plank andsince the planks will ordinarily be assembled in overlapping series,such as indicated in FIG. 2, each plank has secured thereto, on the sameside as the pad 20 but near the opposite end of the plank, a thin planarsheet or pad 36 which will ordinarily be adhered in place, extendingacross the plank, and of rubber non-slip material to engage the nextsucceeding plank and prevent sidewise slippage of the uppermost plank.

It is noteworthy that since lengthwise slippage of the planks ispresented the length of the planks may be shorter than ordinary plainplanks and the saving in plank material offsets the cost of the pads 20and 36.

Obviously the proportions of the pads may be varied and the positioningthereof on the planks and even their number on each plank may beresorted to without departure from the spirit and scope of thisinvention, but what I claim as new and wish to secured by Letters Patentis:
